A bill to amend the Internal Revenue Code of 1986 to maintain the prohibition on allowing any deduction or credit associated with a trade or business involved in trafficking marijuana.

This bill prohibits federal tax deductions or credits for businesses involved in marijuana trafficking, maintaining the current tax treatment under Section 280E of the Internal Revenue Code. It directly affects businesses operating in the legal marijuana industry (where permitted by state law) by preventing them from deducting ordinary business expenses like rent or supplies on federal tax returns. The key provision expands the existing rule to explicitly include marijuana trafficking under federal law, regardless of state legalization. This policy change means marijuana businesses cannot use standard business expense deductions for federal tax purposes, aligning with federal prohibition on marijuana.
